It’s safe to say we’ve all dreamed of exacting workplace revenge at one time in our working life, particularly if you’ve been unfairly dismissed. However, as you’ll read in this article, some disgruntled workers have truly taken their revenge plans too far.
In this article, we look at some of the more extreme cases of workers getting the ultimate workplace revenge on their boss. This includes an IT worker who disabled his employer’s systems by creating a “logic bomb.” Also, a warehouse employee who caused $600 million in damage by torching his employer’s warehouse, and later posted the arson on Instagram.
In early 2024, a Spanish worker got the ultimate workplace revenge on her boss, at the expense of possible jail time. The worker, whose name was never made public, had been employed at the Cepa 21 winery in Spain’s Ribera del Duero region. The woman in her 40s had been a contract worker for the winery before being dismissed. Her employer had decided not to renew her one-year contract.
Two days following her dismissal, the worker decided to get workplace revenge. At 3:30am on 18 February 2024, the worker gained entry into the winery, concealing her identity by wearing a hooded jumper. Security cameras captured the worker moving “smoothly” and with “total familiarity” through the facility in the dark, as described by Cepa 21. She moved directly to the tank room.
The tank room held Cepa 21’s most expensive vintages, Horcajo and Malabrigo, known in the wine industry as “liquid gold.” Within less than a minute, the dismissed worker began opening the valves on the massive stainless steel storage tanks. She knew exactly where to go and exactly what she was doing. Cepa 21 said the worker demonstrated a level of “precision” that only comes from someone who knows the grounds, the security system and the machinery intimately.
The dismissed worker opened five tanks in total. While two were empty, the other three were full of the winery’s most prized assets. Cepa 21 noted that the stainless steel tanks are equipped with specific security mechanisms that make them “very hard to open.” The worker knew exactly how to bypass these locks and manipulate the valves. By the time winery president Jose Moro arrived the next morning to find his tank room flooded, 60,000 litres of premium wine had poured onto the floor. This was equivalent to roughly 80,000 bottles, amounting to around US$2.7 million in value.
The spill wiped out the entire 2023 production of Horcajo, a flagship bottle that retails for around $85 to $90. It also took down a third of the Malabrigo vintage. Mr. Moro told reporters he considered the act an attack not just against Cepa 21, but against the wine sector itself. He called the loss a “sacrilege,” noting that years of work, from vineyard cultivation to careful processing, had been wiped out in minutes.
Meanwhile, online reactions were a mix of shock and solidarity. Some users commented, “Pay your employees well or else. People are not disposable.” The dismissed worker, who lived in a nearby town, was arrested four months after the act of workplace revenge. She was subsequently released on bail while awaiting trial for charges of burglary and property damage. As of 2026, it’s unclear what legal fate the worker faced.
In April 2026, a US worker who railed against his low pay and high cost of living decided to take matters into his own hands. Chamel Abdulkarim worked for NFI Industries, a third-party logistics provider. The company was contracted to operate a warehouse for Kimberly-Clark, located in Ontario, California. The warehouse held hygiene products including Huggies, Kleenex and Cottonelle.
Twenty-nine-year-old Mr. Abdulkarim had a history of disputes with previous employers. In 2024, he filed a class-action lawsuit against aviation services company PrimeFlight. Mr. Abdulkarim alleged that his former employer failed to provide him with mandatory lunch and rest breaks. That case was dismissed in January 2025, likely resulting in an out-of-court settlement.
Leading up to his 2026 workplace revenge, Mr. Abdulkarim had been vocal online about the disparity between warehouse wages and the cost of housing in California. While NFI warehouse workers in the region averaged about $18 an hour (roughly $37,000 a year), the average one-bedroom apartment in Ontario rented out at $2,000 a month.
Mr. Abdulkarim began venting online, saying that the “1% (i.e. the top 1% of income earners) is a f***ing joke.” Mr. Abdulkarim had also vented to an acquaintance about his financial situation. He described himself as being “stuck paying rent on a bulls*** a** apartment that I can’t afford” despite working eight-hour shifts six days a week.
Mr. Abdulkarim’s resentment boiled over during his shift at the warehouse on the morning of Tuesday, April 7, 2026. At 12:30 a.m, he began moving through the 1.2-million-square-foot facility using a lighter to ignite pallets of paper products. Mr. Abdulkarim filmed his arson attack and later posted the video to his Instagram. The video showed him walking from pallet to pallet, targeting highly flammable inventory while voicing his grievances about his pay and cost of living.
This included saying, “If you’re not going to pay us enough to f*cking live or afford to live, at least pay us enough not to do this sh*t.” As he torched inventory, Mr. Abdulkarim also said, “Should have paid us more. There goes your inventory.” He also railed against his corporate overseers, saying, “Pay us more of the value WE bring. Not corporate. Didn’t see the shareholders picking up a shift.”
The fire escalated with extreme speed and quickly overwhelmed the building’s sprinkler system. More than 140 firefighters arrived to fight the blaze. But they were soon forced to retreat from the interior and transition to an exterior-only operation. The warehouse roof later collapsed, and while the facility continued to burn, police arrested Mr. Abdulkarim in the immediate vicinity.
It took eight hours for firefighters to bring the fire under control, which had completely gutted the warehouse. Initial property estimates valued the building at US$156 million. However, once destroyed inventory and supply chain disruptions were accounted for, prosecutors estimated total damages at US$600 million. All employees escaped the building without physical injury, though the facility was rendered permanently unusable.
As of April 2026, Mr. Abdulkarim is currently held in custody without bail, facing multiple criminal charges. Given the scale of the damage and the endangerment of lives, a conviction could result in life imprisonment. Prosecutors allege that Mr. Abdulkarim’s was influenced by contemporary anti-corporate sentiment. Following the blaze, he allegedly sent a text message to a coworker comparing his actions to those of Luigi Mangione, who was arrested for the December 2024 killing of UnitedHealthcare CEO Brian Thompson.
Mr. Abdulkarim also allegedly told the coworker that “a lot of people are going to understand” why he did it. Ironically, the actual victims of his workplace revenge were his colleagues. Due to the warehouse being completely gutted, all staff were dismissed as there was no more work for them. Meanwhile, Kimberly-Clark stated that its insurance would cover the financial hit.
In 2025, a Chinese software developer faced justice for his act of workplace revenge. Christopher Lu lived in Houston, Texas and worked as a senior developer for global power management company Eaton Corporation. In 2018, the company underwent a restructuring that resulted in his demotion.
Upset with the demotion, the 49-year-old Mr. Lu used his administrative privileges to plant logic bombs in the company’s IT systems. Logic bombs are scripts programmed to execute once specific conditions are met. Mr. Lu’s logic bomb was programmed to cause maximum devastation to Eaton Corporation’s staff and global operations. He designed it so it would self-execute shortly after his last day at the company.
As part of his logic bomb, Mr. Lu created a Java-based infinite loop that would force production servers to spawn threads until they crashed. He also created a script titled IsDLEnabledinAD. This program monitored the status of his own user ID so that when his account was deactivated, the script automatically deleted the Active Directory profiles of other employees.
On September 9, 2019, when the company finally suspended Lu’s employment and revoked his network access, the malware detected the change. Because Lu was no longer enabled in the system, his code automatically triggered a massive “kill switch.” Thousands of Eaton Corporation’s employees worldwide were locked out of their work accounts and their user profiles were deleted. The kill switch also resulted in critical production servers crashing after being forced into “infinite loops” that exhausted system resources. All this paralysed the company’s global operations and caused hundreds of thousands of dollars in damages.
Despite his technical nous, Mr. Lu was not able to hide his digital trail. The malicious code was uploaded using his own corporate credentials. Forensic analysis of his company laptop revealed internet searches for methods to escalate privileges, conceal processes and delete files rapidly. Investigators also discovered that Mr. Lu had attempted to delete encrypted data from his laptop before returning it to his employer
In March 2025, a federal jury found Mr. Lu guilty of intentionally damaging protected computers. In August of that year, he was sentenced to 48 months in prison followed by three years of supervised release.
This final story is a less extreme form of workplace revenge, but still very much one that hurt the employer, forcing them to cough up over $14,000 for an unfair dismissal payout. The revenge was detailed in the unfair dismissal NSW case Ms. Dupinder Kaur v Adecco Industrial Australia Pty Ltd [2025]. Sydney-based Dupinder Kaur started working for Adecco in October 2024.
Throughout her seven months at the company, she was placed at an Amazon distribution centre as a pick packing associate. Despite being a casual, Ms. Kaur worked full-time hours and had a completely unblemished service record. Her duties involved picking parcels, using ladders, and scanning items, earning her an average of $1,426 per week.
The events that led to her termination of employment began on 25 May 2025. Ms. Kaur informed an Adecco employee that she was around seven weeks pregnant and was feeling dizzy while using ladders. She provided medical certificates advising that she should not lift weights heavier than 5kg and should avoid stairs and bending.
However, the certificates explicitly stated she was otherwise “fit to work.” In response, Adecco immediately cancelled her scheduled training for a “Packing” role and placed her shifts “on hold.” Despite the restrictions, Ms. Kaur worked two night shifts on light duties on 1-2 June 2025.
However, at 2:04 am on 5 June 2025, she received a lengthy SMS from Adecco. The message stated that because of her lifting restrictions and lack of training in other areas, no further light duties could be offered. It claimed her “shifts will be put on hold” and reminded her that as a casual, there was “no guarantee of work.”
Ms. Kaur pushed back immediately via SMS and email. She pointed out that she had just completed two light-duty shifts and that the training she required had been cancelled by the company. She wrote that she had disclosed her pregnancy to “get support, not to get laid off,” describing the situation as “unfair and discriminated behaviour.” Adecco failed to respond to her correspondence and offered no further shifts. Ms. Kaur subsequently lodged a Fair Work unfair dismissal claim.
Adecco raised a jurisdictional objection to Ms. Kaur’s Fair Work unfair dismissal claim. The company argued that no dismissal had occurred because Ms. Kaur remained an employee with an “active profile.” The company contended that it had shifts available to give her, but that it wasn’t giving them to her because she claimed she was fired. Adecco also argued that Ms. Kaur’s Fair Work unfair dismissal claim itself had “interrupted” its efforts to find her work.
Alternatively, the employer argued that if a dismissal had occurred, there was a valid reason based on Ms. Kaur’s “capacity.” It pointed to the physical requirements of the Amazon site, which mandated lifting up to 20kg and constant bending. Adecco submitted that “clear medical evidence” showed she could not perform her role.
Ms. Kaur’s Fair Work unfair dismissal claim was heard by the Fair Work Commission in October 2025. It rejected Adecco’s arguments, ruling that placing shifts “on hold” indefinitely with no return date constituted a termination of employment. The Commission described the SMS as a “mixture of people and culture puffery and lawyerly disclaimers.” It found that “the substance” of the SMS was that Ms. Kaur’s employment was on hold from 5 June 2025 “until the 12th of Never.”
The Commission further found there was no valid reason for the dismissal. It noted that Ms. Kaur had successfully performed light duties just days prior, meaning her medical restrictions were not insurmountable. It slammed Adecco for failing to provide evidence regarding who made the decision to stop her shifts or why light duties suddenly became “unavailable.”
Regarding procedural fairness, the Commission found that Ms. Kaur was given no opportunity to respond to the reasons for her dismissal. It noted that as a large enterprise with dedicated HR expertise, Adecco’s failure to consult with Ms. Kaur or respond to her emails was “unreasonable.” The Commission stated that Ms. Kaur “deserved a response” as a matter of “common decency.”
Ultimately, the Fair Work Commission ruled the dismissal was harsh, unjust and unreasonable. Finding that the relationship could be restored, the Commission ordered Ms. Kaur to be reinstated to her former position. Adecco was also ordered to pay her $14,830.40 in lost remuneration plus superannuation and to maintain her continuity of service.
